2 Python Tutorial for Beginners _ Python Installation _ PyCharm

Episode Transcript

Speaker 1 (00:00):
Welcome back, aliens. My name is Devan Reddy, and in
this video, we'll talk about the Python installation. The thing is,
we have talked about a language which is very powerful,
but then where you will write your code? Of course,
we can simply open your notepad, and we can write
the code which we want, right? So example, I can
simply go back here, and I can say, okay, what
type of code I want to write? So it can

(00:21):
be anything. It can be, let's say, two plus three. Now,
when you say you want to write a code, it
can be a calculation, a computation. So basically, a normal
calculation like adding two numbers, or deciding in which stock
to invest, or maybe deciding who should be the next CEO.
So basically the idea is, if you want to write
a code to design a software which can do some activities,

(00:44):
we have to write a code, but where? If you
write the code in the notepad, of course you're not
getting the output. Where do you get the output for this?
This is tricky, right? And that's why in your machine,
you need a Python interpreter. So basically, we have to
install some software. And in this machine, I don't have it.
How do I verify? It's very simple. You can open
your command prompt. So if you're using Windows, you can

(01:06):
use command prompt to check it. Or if you're using
Mac or Linux... you can open the terminal so i'm
here on command prompt and here let me see if
i have python now basically the way you can check
that is by saying python version and if you get
this type of error which which says python was not
found that means in this machine i don't have python

(01:27):
okay with python 3 you might also check if do
you have python 3 installed and you can see nothing
is there So even if you have Python installed, sometimes
it will not work with the Python command. It might
work for the Python 3 command. So do check both
the versions. And in this machine, I don't have any.
So how do you get it? So the first thing
we need is Python interpreter. And, okay, let's say we

(01:49):
got Python interpreter, and then you can write a code there.
The thing is, in the interpreter, it provides you an
option of writing a code one line at a time. So,
of course, you can add two numbers. But what if
you want to build a big project. Now it can
be a scientific project or an AI project. Now that's
what is booming nowadays. So if you want to build

(02:11):
an AI project or a web application, or a desktop
application where you will do it. For that, you need
a software where you can write the code, test your code,
run your code, debug your code, and also deploy your
code to the cloud where you will do it. Now
that's why we have to use something called an IDE,
which stands for integrated development environment. Now for Python, we

(02:33):
have a lot of options. Now one is very famous,
which is your PyCharm. Now this is from JetBrains. Again,
in this video, I will show you how to install
Python interpreter and the PyCharm. So let's start with the interpreter.
So what you will do is, in fact, in the
updated version of Windows, when you say Python enter, it
will open the Microsoft store. But let's say if you

(02:56):
don't have this configured, that's fine. What you can do
is you can just go to Google and search for
Python download so you can say this is the option
you will get so of course the first website says
Python you can download it from here. Now in the
upcoming videos you might see a different version of Python
install and that's completely fine because in the version difference
you will not find a lot of changes so even

(03:16):
those things those code will work here. Okay so you
can go for Python 3.12 which is the latest version
I feel so if I click on download so you
can see we got download Python 3.12, so you can
download this version. 13 is into pre-release, so don't use
13 at this point. We got 12, which is 3.12.

(03:37):
So we can click here and say download. So you
can see it is downloading and downloading complete, I feel. Yeah,
that's done. Now, depending upon which OS you have, Windows, Linux,
or Mac, depending upon that, you can choose from here.
So you can see we have different options here. and
uh yeah so that's the thing so let me click

(03:58):
on this and install so basically i don't have this
installed so i will just click here and now this
will install the software okay so you can see we
have an option here which is install now or customize
i will go for simple installation But before doing that,
I also want to say add a python.exe to the path. Basically,
even if you have installed, maybe whenever you open a
different folder, Python may not be available there. So if

(04:20):
you do this, add a python.exe to your path, you
don't have to manually search for the installation. So you
can click on this, install now, and it will take
some time. Now if you skip that step of add
to the path, Then you have to manually set the path.
But anyway, when you do the add to path, you
don't have to do the other steps. So by the

(04:40):
time it is getting installed, what we can do is
we can also get the PyCharm downloads done. So I
will search for PyCharm. Now PyCharm is from JetBrains, which
is a very famous company for the IDs and software tools.
So it helps developers. Now basically, you can also use
VS Code for Python. You can also use Anaconda or IDLA,
which is the interpreter and many more. So I will

(05:02):
just click on this. I will say download PyCharm. The
thing is when you download or when you go to
the PyCharm, it's not actually free. Now that's a twist, right?
So we have two versions there. One is a paid version,
one is a free version. So I would encourage you
to go for the free version. But yes, once you
become a professional, once you're working for a company, then
it makes sense to use the paid version. So this

(05:24):
is the website. And as I mentioned, this is developed
by JetBrains, which is the website here. It's also the company.
And we also have a community version. So if you
want the community version, you can scroll down and you
can see we have two different versions, professional and community.
I will click on the community version. If you go
for the professional version, you will get trial for one month.

(05:46):
So you decide if you want to use it or not.
But I would encourage you to use the community version.
So this is getting downloaded. Let me go back to
my Python setup. And looks like Python setup is completed.
Let me click on close. So setup is complete. How
do I verify? Again, we have to go to command prompt.
Now one thing to remember, even if you have installed
Python and if you directly do this, it may not work.

(06:09):
So you have to reopen your command prompt. So now
if I say cmd, and let me try now, python version.
And you can see we got Python installed. This time
we are getting a version number. We're not getting that
error which was getting earlier. So yeah, Python is installed.
Now how do I test it? It's very simple. You
simply say Python, it will open the interpreter. Now this

(06:29):
is where you can write a code. Of course, it
doesn't look good, right? Maybe you need a software where
you will find, in fact, if you have learned some
other languages, you can write the code, you can see
the project, you can run the code, We'll see that
in PyCharm. But here, you can see we got the interpreter.
And here, I can simply add those two numbers. And
it is working, right? So you can do calculations, computations,

(06:52):
whatever you can do in this prompt. Apart from this,
if you want to open Python, you can also search
for Python. So you can see it will also give
you an app. So you can also use this one.
This is the IDLE from Python. In fact, IDLE looks
like something like this. So this is the Python interpreter.
you can also use ideally yeah i know white theme
a lot of people don't like it but for youtube

(07:13):
videos you know it makes sense to have a light
theme it looks good it also encourages you to learn
more but anyway that's your choice if you want to
use a white or black or dark especially for me
i prefer to use dark theme when i'm coding and
for videos i prefer white themes anyway that's a different
debate uh so i can just use this i can
also say two plus three here i'm not sure if

(07:33):
the font is visible but that's not important If I
say two plus three, enter. Okay, we got syntax error. Again,
I will say 2.3. I think I've entered something weird. Okay,
so you can see we got five there. So yeah,
you can do this here. You can do that here
or in the command prompt, which we have opened earlier.
But what about the PyCharm? So we got the PyCharm
installation done. So you can see we got PyCharm download complete.

(07:55):
I will click on that, taking some time. And if
you can see, yes. Okay, now setup is very simple here.
You just have to say next, next. It will detect
the Python as well, the setup. I'll click on next, install. Again,
we'll take some time. Okay, it looks like a bulky software.
It is doing a lot of extraction. But that's the
thing with IDEs, you know, they are bulky. Otherwise, you

(08:16):
can also use VS Code if you want. That's your
personal choice. Everything which we are doing in PyCharm or
on the IDLE, it will also work on VS Code. Okay,
setup complete. And I can also say run here from
here or I can simply click on finish. Let me
open PyCharm, taking some time again. Okay, I don't want
to import these settings and import, click on okay. So

(08:38):
basically I'm using PyCharm on this machine for the first time.
So you will get some extra prompts. Okay, so what
you can do here is you can create a project.
You can name any project, you can name anything you want.
I can click on create. And voila, you got your
project here. So this is how the PyCharm looks like.
And that's your Python code. Again, don't get confused with

(08:59):
the code here. We'll understand this one step by step.
But this is your Python code here. You can even
run this if you want, but it will take some time. Anyway,
we are going to see the PyCharm, how to use
it later in the course. So yeah, that's it from
this video where we have the setup for the Python
interpreter and PyCharm. So if you are enjoying this series,

(09:20):
hit the bell icon because that's how you will know
when I upload the other videos on the platform.
